1. A method performed by a receive (Rx) UE for sidelink Vehicle-to-Everything (V2X) communication, comprising:
decoding, using blind detection, a first-stage Sidelink Control Information (SCI) in a received signal, wherein the first-stage SCI contains control information for the Rx UE to locate time-and-frequency resources used by a transmit (Tx) UE, and wherein the time-and-frequency resources are used to transmit the first-stage SCI via a Physical Sidelink Control Channel (PSCCH) and to transmit a second-stage SCI and data via a Physical Sidelink Shared Channel (PSSCH) associated with the PSCCH; and
locating the second-stage SCI in the time-and-frequency resources based on the first-stage SCI, wherein the second-stage SCI contains additional control information from the Tx UE to the Rx UE for the sidelink V2X communication,
wherein the second-stage SCI contains the additional control information which includes a source identifier and a destination identifier.
